About the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75
The AirTAC SAIJ160X210-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 210 mm travel by up to 75 mm. This creates a highly flexible 135-210 mm usable positioning window, perfect for dialing in exact end stops during machine commissioning without swapping hardware. Built with a SUS304 stainless steel rod, it handles heavy loads with 10053 N of pull force at 0.5 MPa.
This heavy-duty actuator features a robust 40 mm rod and M36x2 thread, providing substantial rigidity against side loading. The extruded aluminum barrel incorporates sensor grooves on both sides, and because this unit lacks a magnet, you would need to specify the -S option to utilize AirTAC CMSE reed or DMSE electronic solid-state sensors. The rear stopper acts purely as a travel limit and works alongside the standard adjustable air cushions to decelerate the payload smoothly.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75 Is Used
Heavy Machinery Setup
Fine-tune the 135-210 mm retraction end-stop during initial commissioning of large presses to achieve perfect material seating without machining custom spacers.
Product Size Changeovers
Quickly adapt a packaging line for different carton depths by rotating the rear adjuster screw to shift the 210 mm stroke back by up to 75 mm.
Variable End Positioning
Dial in the exact clamping distance on an assembly fixture, using the rear stopper to set a precise lower bound within the 135-210 mm travel window.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75 the Right Cylinder?
Selecting this 160 mm bore actuator makes sense when your application requires substantial push force—up to 14074 N at 0.7 MPa—combined with variable end positioning. If your setup needs less force, stepping down to a 125 mm bore yields 6136 N of push at 0.5 MPa, but the SAIJ160X210-75 provides the heavy-duty margin needed for large product changeovers. When matching ISO 15552 replacements, verify the 210 mm stroke, 75 mm adjustment range, PT tapered port threads, and the specific mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
Because the nominal stroke is 210 mm, you should ensure adequate external guiding to prevent excessive side loads on the rod. Remember that the rear adjuster is a mechanical stop, not a locking device; this cylinder will not hold its load without live air pressure. For fail-safe load holding, consider an external pilot-operated check valve or explore the AirTAC SAIL or BSAI locking cylinder series instead.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160BX210-75 FAQ
At 0.5 MPa operating pressure, this 160 mm bore cylinder provides 10053 N of push force and 9425 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 14074 N.
The rear adjuster screw allows you to reduce the nominal 210 mm stroke by up to 75 mm, providing an effective travel window of 135 to 210 mm. This stopper only limits the travel end and does not lock the load without continuous air pressure.
